Abstract: Technologies for on-device experimentation include embodiments that receive a request to provide digital content for display in a slot of a user interface display screen of a first device. By a secure execution environment, an identifier received with the request is anonymized. The request is determined to be associated with a content distribution test. The anonymized identifier is assigned to a test group associated with the content distribution test. The secure execution environment receives user interface event data generated by the first device in response to the content distribution test. The received user interface event data is attributed to the test group. An association of the user interface event data with the test group and the content distribution test is provided by the secure execution environment to a second device different than the first device while the identifier and the anonymized identifier are not provided to the second device.

Abstract: Devices and methods for purifying lithium from lithium salts, including those with low concentration of lithium salts, are provided. A molten composition comprising a lithium salt is electrolyzed with an anode in contact with the molten composition and a cathode separated from the molten composition by a solid electrolyte capable of conducting lithium ions.

Abstract: Technologies for a flexible three-dimensional power plane in a chassis are disclosed. In one embodiment, a flexible ribbon cable is laid along a circuit board tray. The flexible ribbon cable is secured to the tray using power bosses. The power bosses connect to one or more conductors on the ribbon cable. When the circuit board is mounted on the circuit board tray, the power bosses extend through holes in the circuit board and mate with power clips on the surface of the circuit board tray. The ribbon cable, power bosses, and power clips can distribute power to various locations on the circuit board, without requiring large traces that take up space on the circuit board.

Abstract: The present invention which relates to the field of offshore wind turbine installation technology, discloses a wind turbine holding and lifting system for a movable operating platform above water. The wind turbine holding and lifting system comprises a door-type installation frame, a wind turbine lifting device and enclasping means for clamping the wind turbine tower, the door-type installation frame including a first leg, a second leg and no less than one beam fixed between the first and second legs, the wind turbine lifting device being attached to the door-type installation frame with its lifting end connected to the wind turbine tower. The wind turbine holding and lifting system with such a structure is available for a movable operating platform above water, the enclasping means and the wind turbine lifting device of the wind turbine holding and lifting system being capable of completely constraining the wind turbine such that the assembled wind turbine can be fixed in a wind turbine installation state.

Abstract: The present invention discloses a support leg and a mobile offshore work platform having that leg. The disclosed support leg for a mobile offshore work platform comprises a support arm extending in a vertical direction, further comprising a support platform that has a cross section larger than that of the support arm, and that the lower end of said support arm is fixed to the upper surface of the support platform. When wind turbine installations or other offshore works are carried in sea areas of soft foundation ground, the support platform is supported on a soft foundation ground by a larger cross-sectional area, providing a greater support force and improving the stability of the mobile offshore work platform, and the mobile offshore work platform can be used to complete wind turbine installations and other predetermined works in sea areas of soft foundation ground.

Abstract: The present invention discloses a gravity center adjustment device for a wind turbine installation vessel, with the gravity center adjustment device (2) fixedly mounted to the outside of the vessel body (4) of the wind turbine installation vessel. The existence of the gravity center adjustment device (2) according to the present invention is independent from the vessel body and no longer limited by the size of the installation vessel and the size of the ballast bank provided in the vessel body of the wind turbine installation vessel. The size of the gravity center adjustment device (2) may be set as desired so that the adjustment ability of the gravity center adjustment device can be changed, whereby its ability for adjusting gravity center of the wind turbine installation vessel can be improved and the stability of the wind turbine installation vessel can be improved.

Abstract: The present invention which relates to the field of offshore wind turbine installation technology, discloses a wind turbine holding and lifting system for a movable operating platform above water. The wind turbine holding and lifting system comprises a first standing column, a second standing column, a beam lifting device, no less than one beam and enclasping means for holding the wind turbine tower; the first standing column and the second standing column are juxtaposed, and the opposed faces of the first and second standing columns are provided with guiding grooves for sliding the beams; the enclasping means is arranged on the beam, and the two ends of the beam are interfitted within the guiding grooves of the first and second standing columns; the beam lifting device is fixed to the first or second standing column, and the lifting end of the beam lifting device is connected to the beam.

Abstract: The invention relates to a foundation construction platform adapted for foundation construction in a beach or offshore areas. The platform comprises a platform body (1), outriggers (5) mounted on the bottom of the platform body (1), a first hoisting frame (11) and first slide rails (21) longitudinally disposed along the platform body (1), the first hoisting frame (11) having a first lifting member (31) attached to the first transverse beam (111) thereof and the first hoisting frame (11) being capable of sliding along the first slide rails (21). Without other auxiliary equipments, such as, a crane, the operations like removing or rotating a pile can be carried out to decrease the number of the auxiliary equipments on a foundation construction platform so as to reduce the operation cost of the foundation construction platform. The present invention also provides a foundation construction platform including above mentioned hoisting equipments.

Abstract: The present invention discloses a gravity center adjustment device (2) for a wind turbine installation vessel. The gravity center adjustment device (2) is movably mounted to an outside of a vessel body (4) of the wind turbine installation vessel, so that the gravity center adjustment device (2) can selectively move in a plane substantially parallel with the vessel body (4). Since the gravity center adjustment device (2) according to the invention is movably installed to the vessel body and can move in a plane substantially parallel with the vessel body (4) so as to adjust the horizontal position of the gravity center of the installation vessel, its ability of adjusting the gravity center of the wind turbine installation vessel can be improved and the stability of the wind turbine installation vessel can be improved. Therefore, the operation efficiency can be improved and the cost of constructing a wind power plant on the offshore can be reduced.
